Appeal No. 1998-1412 Application No. 08/397,124 density polyethylene having a green interference pigment and a blue colorant dispersed therein. These sheets can be cut into pieces and mounted between two pieces of glass. (Column 6, lines 8-31). Armanini discloses the transmission color is determined by holding the object, e.g. slides, to daylight to observe the colors produced. (Column 3, lines 57-66). Accordingly, we conclude that the sheets function as a solar screening material within the scope of the claimed subject matter. The claimed invention is directed to a composite, suitable for use as a solar radiation screening material, comprising a green interference pigment and a transparent polymer. Armanini’s Example 4 describes a composite material within the scope of claim 12. The material of Example 4 is said to have a purple transmission color. (Column 6, lines 26-27). Armanini discloses the transmission color of the formed products are determined by viewing the products visually in daylight. (Column 3, line 57 to column 4, line 1). Thus, the determination of the transmission color of the Example 4 product would also function to screen solar radiation from the daylight. Appellants urge Armanini is directed to decorative effects and there is no motivation to deduce the present invention. Appellants also urge, “the use of Armanini’s article as covering for greenhouses would have the disadvantage that incident light which is utilizable for the plant would be absorbed by the absorption pigment.” (Brief, paragraph bridging pages 4 and 5).
